Built solo from the ground up, EM Coach delivers medical education content to US doctors and residents. Learners can choose to study either on their own, at the direction on an institutional instructor, or by following the coach, an automated assistant that assess the learner's needs and generate a unique 15 minute lesson based on the learner's needs, while also throwing in a bit of what they excel at to ensure retention of the learner's strengths. Education content is written and reviewed by board certified Emergency Medicine Physicians. Each piece of content is created in 3 forms: practice tests, textbook readings, and lectures. This provides differentiated instruction to the learner and empowers them to seamlessly switch between content types if they need additional clarification and support.

This content management system (CMS) accompanied by an admin portal is used to manage and supply content to registered users. Registered users have their own profile, adaptive preferences, and are hooked up to an auto-pay subscription system.
